The information and specifications in this technical
specification is believed to be correct at the time of
publication. However, no liability is accepted for
inaccuracies, printing errors or for any consequences
thereof. Ericsson AB reserves the right to change the
contents of this technical specification at any time without
prior notice.
Note : As an example a positive logic, increased standoff, short pin product
would be PKB 4711 PIPNBMLA.
Reliability
The failure rate (
λ
) and mean time between failures (MTBF=
1/
λ
) is calculated at max output power and an operating
ambient temperature (T
A
) of +40°C. Ericsson Power
Modules uses Telcordia SR-332 Issue 2 Method 1 to
calculate the mean steady-state failure rate and standard
deviation (
σ
).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate,
λ
214 nFailures/h
Std. deviation,
σ
34.5 nFailures/h
MTBF (mean value) for the PKB series = 4.7 Mh.
MTBF at 90% confidence level = 3.9 Mh
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have
a maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products are found in the Statement of
Compliance document.
Ericsson Power Modules fulfills and will continuously fulfill
all its obligations under regulation (EC) No 1907/2006
concerning the registration, evaluation, authorization and
restriction of chemicals (REACH) as they enter into force
and is through product materials declarations preparing for
the obligations to communicate information on substances
in the products.
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, Six Sigma, and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
